Lucy purchased 5 equally-priced shirts for $60. Frank bought 4 shirts. Each of his shirts were $2 more than the price of a shirt Lucy purchased. How much did Frank spend on his entire purchase? Hel pls!!!

$56

Step-by-step explanation:

Lucy's shirts were $12 each since 60/5 is 12. Frank's shirts were 2 more than lucys so his were $14. 14 times 4 is 56.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
